She (usually) has a very proportionate body and beautiful legs. One of the very few celebs that I like at an average weight. But I feel she has become smug after her first pregnancy, when everybody complimented her style. That dress she wore in Cannes is such a faux pas for looking emphasizing all her lumps!
Honestly, I doubt she's smug. I think if your married to Ryan Reynolds you kind of have to have a sense of humor because he's so candid/revealing. Plus I'm pretty sure all of her movies have been comedies because they're all hilarious (especially Savages, laughed my ass off at that mess)
Also, I'm not sure what she's supposed to wear by our standards when she is both recently pregnant & currently pregnant. It might be a little clingy, it might have cutouts, but I think overall it's a fine dress for her body. It's not egregiously revealing compared to plenty of other celebs who aren't even pregnant. The dress is just the style of the times, which isn't her fault.
EDIT: Oh god, I take everything about that dress back. This is what she wore yesterday or today
